From the developer:
Langwitch is a simple FREE utility for Mac OS X that makes switching between the keyboard layouts very easy! Simply set the individual hotkey for each language you use and you won't have to switch through all languages every time you need to use a particular one.
There is also no need to check which keyboard layout is selected right now. With Langwitch you can switch to the needed language momentarily!
